SPECIFICATION forming part of Letters Patent No. 714,458, dated November 25, 1902. Application ieanprn as, 190e. "sena No. 104.276. dit moda.)

` To all whom it may oon/cern.-

Be it known that we, LEwIs DAL'roN and DICK CROSS, citizens of the United States, and resident-s of Santo, in the county of Palo Pinto and State of Texas, have invented a new and Improved Lock, of which the following is a full, clear, and exact description.

Our invention relates to an improvement in combination-locks for doors, safes, bureaus, and the like which is simple in construction and provided `with readily-operated means forholding the combination-disks inactive and in position to permit a locking-bolt to be freely operated by a key when so desired, which means will also permit the combination to be set so that the bolt cannot be moved by a key until the disks of thecombination have been brought to proper. position to permit of an unlocking movement of the bolt, where-` by the lock can be used as a combinationlock or as an ordinary lock and will perform both functions in a perfect manner. The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

. Reference is to be had to the accompanying drawings, forming a part of this specification in which similar characters of reference indicate corresponding parts in all the igures.

Figure 1 is aside elevation of the improved lock. Fig. 2 is a side elevation of the lock with the front plate removed and the combination-knob spindlein section, and Fig. 3 is a longitudinal sec-tion through a portion of the lock and through the combination-disks therefor.

The casing A of the' lock is provided withl the usual removable side plate 10, and a spin-` dle 11 is passed through the lock from side to side, turning loosely in the` casing. This spindle is shown located'at one side` or cention-disks are mounted to loosely turn, three of said disks being illustrated, (designated, respectively, as 15, 16, and 17.) The outer disk 15 of the one nearest the side of the cas ing is separated from the casing by a washer 18, and similaiwashers 19 and 20 separate the disks 15 and 16 and the disks 16 and 17. Each disk 15, 16, and 17 is provided with a peripheral recess 21, of any desired depth and size, and a peripheral slot 22, about a `quarter of the circle `distant from the said recess, as is shown in Fig. 2. The inner disk 17 is provided at its face removed from the other disks with two opposing pins 23, and projections 24 from the spindle 11 extend between the pins 23 and engage therewith as the spindle 11 is turned to revolve the said` disk 17'. A stud 25 extends from the opposite side of the disk 17 to within a short distance of the opposing disk 16, as is shown in Figs. 2 and 3, and this stud 25 is located opposite the recess 21 in the said disk 17. An outwardly-extending stud 26 is formed upon the face of the disk 16 opposite the disk 17, and the stud 26 is located, as shown in Fig. 2, between the recess 21 in the disk 16 and the slot 22, nearer the said slot than to the said recess. A second stud 27 extends from the opposite face of the disk 16 in alinement with the stud 26, as is shown in Fig. 3, and the stud 27 somewhat closely approaches the inner face of the disk 15, which disk 15 is provided with an outwardly-extending stud 28 between the slot 22 and recess 21 in said disk, but nearer the said recess than the slot. The studs at opposing faces of the disks are so arranged that as the disks are revolved oneis brought in the path of the other, and

`when an engagement is effected between the studs of opposing disks the recesses 21 of the disks will be in alinement and likewise the slots 22.

In the form of the combination shown the spindle 11 is turned a certain distance in one direction, which will move the disk 17, and when the stud 25 of said disk is brought to an engagementnwith the stud 26 on the disk 16 the recesses 21 of the two disks will be brought in alinement, and when turning the spindle 11, for example, in another direction or in the same direction to a given extent the stud 27of the disk 16 will be brought in engage- IOO ment with the stud 2S of the disk 15, and the recess 21 of the disk 15 will then be brought in registry with the recesses ofthe other disks, and the slots 22 of all of the disks will also be in registry. rIhese slots 22 will be immediately beneath the head 29 of a spring-latch 30, secured to the inner wall of the casing A above the disks, the said head 29 of the latch being adapted to enter the slots 22 in the disks, and thus prevent the disks from turning. The head 29 of the latch 30 is thus brought in engagement with the disks when the lock is to be operated solely by a key.

The spring-latch 30 is operated from the exterior of the casing usually through the medium of a thumb-piece 3l, having sliding movement in the casing and connected with a slide 32, located within the casing, which slide when forced between the wall of the casing and the head 29 of the spring-latch 30 will carry the said head of the latch downward to enter the slots 22in the combinationdisks.

When the slots 22 in the combination-disks are in position to receive the head 29 of the latch 30, the alining recesses 21 in the combination-disks will be immediately opposite an extension 33 from the rear end of a locking-bolt 34, which locking-bolt is held to slide in the casing and to project out beyond the same when the bolt is in locking position, and the rear extension 33 of the locking-bolt i's of such dimensions that it will freely enter the recesses 21 in the combination-disks'. When the extension 33 of the locking-bolt thus enters the recesses 2l, the bolt can be drawn inward to unlocking position; but when the unrecessed portions of the combination-disks are presented to the rear extension 33 of the locking-bolt 34 said bolt cannot be drawn inward, but must remain in its outer or locking position. (Shown in Fig. 2.) The locking-bolt 34 may be guided in its movement in any suitable or approved manner. As shown, the bolt is provided with a longitudinal slot 35, in which slot a block 36 extends, said block being secured to the casing of the lock, as is illustrated in Fig. 2, and in the lower edge of the locking-bolt 34 a recess 37 is made.

The recess 37 in the lower edge of the locking-bolt 34 receives a tongue 38 from an end portion of a key-sleeve 39, mounted to turn at its ends in the side plates of the casing, which sleeve will receive a key at either end, and this key-sleeve is provided with a circumferential recess 40,- which extends nearly around the same and is in communication with the key-bore of the sleeve.

Two guide-plates 41 and 42 are secured to one face of the locking-bolt 34, as is shown in Figs. 2 and 3, and these plates enter the circu mferential recess or slot4'0 in the key-sleeve Between these two plates 4l and 42 a locking-plate 43 is located, pivoted at its outer end and provided with an extension 44 at its inner end, which extension is normally held in engagement with an angular post 45 (shownin Fig. 2) through the medium of a spring 46, attached to the outer end of the locking-plate 43 and exerting downward tension upon the extension or head 44 of the said plate at its opposite end. When the head 44 of the locking-plate is in engagement with the post 45, the locking-bolt will be heldin its outer or locking position, as is shown in Fig. 2; but if the combination-disks be set to permit the inward movement of the bolt 34 and a proper key is introduced into the keysleeve 39 and turned a bit of the said key will engage with the locking-plate 43 and force the said plate away from the post 45 to such an extent that the head 44 of the lockingplate will clear the said post, and at the same time as the key is turned the locking-sleeve 39 will be turned also, and its tongue 38 being in the recess 37 of the locking-bolt 34 will move the said bolt inward or outward, as may be required. Thus it will be observed that the lock, although simple in its construction, may be used as a combined combination and key lock or may be used for any length of time as a key-lock only. It will also be uuderstood that the construction of the combination mechanism may be changed Without departing from the spirit of the invention.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a lock, the combination with a casing, a series of combination-disks and means for turning the same, each disk having a peripheral recess, said recesses being adapted to register with each other at one point in the revolution ot` the disks, of a sliding lockingbolt having a rear extension adapted to enter the recesses in the combination-disks when said recesses are in registry, a key-sleeve mounted to revolve and provided with a tongue entering a recess in the bolt, guardplates secured to the bolt and extending be- IOO IIO
